Abstract

Microplastics are particles that have a size of <5 mm and their existence might be able to contaminate the biota in the aquatic environment, such as care fish. Caru fish was collected in the Dumai city fish landing base in September - December 2022 to determine the abundance of microplastics in caru fish. The method used in this study is a survey method; samples of caru fish were obtained from Fish Landing Base (PPI) Dumai, and the samples were analyzed for the microplastic content in the laboratory. The samples used were 90 caru fish divided into three size classes. The parameters measured included type of microplastic, microplastic abundance, microplastic colour and the relationship between care fish size and microplastic abundance. The abundance of microplastics from the three size class of fish shows that the size class 22.1-24 cm had a higher average abundance of microplastics with an average value of 5.7 particles/individual. The type of microplastics found in this study were fibre, film and fragment. The relationship between the length of the caru fish and the abundance of microplastics has not been influenced by the size of the carp fish.

Abstract

Striped catfish (Pangasianodon hypophthalmus) is a widely cultivated type of superior food fish. Intensive cultivation of catfish can cause disease. Feeding striped catfish with guava leaf extract is expected to reduce stress, which can be seen in striped catfish's hematological and physiological conditions. This research aims to obtain a dose of guava leaf extract (Psidium guajava L) to improve the health of striped catfish. The method used in the study was an experimental method that applied a one-factor, Completely Randomized Design (CRD) with five treatment levels. The treatment used was without adding guava leaf extract (P0); P1, P2, P3, and P4 with doses of 25, 50, 75, and 100 mL/kg feed, and all treatments were tested against Aeromonas hydrophila. The fish used in this research were 250 striped catfish seeds measuring 6-8 cm and kept for 45 days. Feeding with the addition of guava leaf extract at a dose of 75 mL/kg of feed had an influence on the hematological and physiological profile of post-challenge catfish, such as total erythrocytes of 2.40x106 cells/mm3, hematocrit 35.66%, hemoglobin levels 9.61 g/dL, total leukocytes 10.54x 104 cells/mm3, blood glucose levels of 78.00 mg/dL and phagocytic activity 35.66%. Absolute weight growth 17.76 g, feed efficiency 41.07%.

Abstract

Moringa is one of the plants with high nutrients and antioxidants and can improve fish's immune system. This study aimed to look at the structure of the skin and kidney tissue of striped catfish fed with feed containing Moringa leaf flour after being tested for Aeromonas hydrophila bacteria. This research was conducted from January to May 2024 at the Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau, and fish histology observations were made at the Aquatic Biology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. The method used in this study is an experimental method by applying a one-factor Completely Randomized Design (CRD) with five levels of treatment and three replicates, namely KN (without moringa leaves and A. hydrophila challenge test), KP (without moringa leaves and challenged with A. hydrophila), P1 (dose of 10 g/kg feed), P2 (dose of 15 g/kg feed), P3 (dose of 20 g/kg feed). The results showed that most organ tissues were still in a normal state. The best dose of moringa flour addition to feed is 10 g/kg feed (P1). Fish tissue structure in P1 has damage such as hypertrophy, hemorrhage, and lipofuscin pigment on fish skin. Fish survival during the study was 97.67%.

Abstract

The freshwater lobster (Cherax quadricarinatus) is a precious commodity within the freshwater aquaculture sector. It is essential to investigate the effects of different natural feeds on lobster growth to enhance aquaculture practices. This study aimed to identify the types of natural feed that influence and improve freshwater lobster juveniles' growth and survival rate. This study was conducted from January to February 2024 at the Kasih Karunia Suwawa Aquaculture Hatchery. A Completely Randomized Design (CRD) was applied, with four treatment groups: Treatment A (bean sprouts), Treatment B (Tubifex sp.), Treatment C (tofu residue), and Treatment D (a combination of bean sprouts, Tubifex sp., and tofu residue). The feed was administered daily at 7% of the total biomass, with a feeding frequency of twice per day. Data were analyzed using ANOVA with SPSS software. The observed parameters included length growth, weight growth, survival rate, and moulting frequency. The results showed that Treatment B (Tubifex sp.) yielded the best growth and moulting frequency, with length growth at 0.76 cm, weight growth at 0.70 g, and moulting frequency at 0.67. The highest survival rate, at 96.67%, was observed in Treatment D (bean sprouts + Tubifex sp. + tofu residue). ANOVA results indicated that different types of natural feeds did not significantly impact the growth and survival of freshwater lobsters.

Abstract

This research aims to determine the use of rice straw as a packaging medium for the survival, growth, induction, and sedation of lobster seeds transported for 6, 9, and 12 hours using the Completely Randomized Design (CRD) method. The research preparation includes preparing the maintenance medium, filling medium, and test animals (adaptation for 7 days after arrival and fasting for 24 hours). The main research involves acclimating lobster seeds using temperature manipulation for approximately 5 minutes, with transport media temperatures ranging from 10º to 12º, and then maintaining them for 28 days. The research results indicate survival, growth, induction, and sedation time differences. The fastest induction time occurred in the treatment with a 9-hour transport duration, lasting 4.14 minutes. The fastest sedation time occurred in the 6-hour transport duration, lasting 1.56 minutes. Post-transport survival is highest after 6 hours and 9 hours of treatment, which is 95%. The best post-maintenance survival is found after 6 hours of transportation, at 91%, while the treatments at 9 and 12 hours yield 86% and 76% results, respectively. This research indicates that straw can be utilized as a filling medium for up to 12 hours.

Abstract

Funding for fishermen's enterprises refers to the costs fishermen require to procure investment goods and operational costs for fishing activities. Funding for fishermen's enterprises is sourced from various channels. This research was conducted in May 2024 in Kuala Indragiri District, Indragiri Hilir Regency, Riau Province. The research has two objectives: first, to describe the procedures for funding fishermen's enterprises. The second objective is to determine the influence of funding procedures and the socio-economic conditions of fishermen on the decision to borrow from non-formal sources. The sample consisted of 79 fishermen from 3 villages selected using the purposive sampling. Data collection was done through interviews, documentation, and questionnaires. Data analysis was conducted using Descriptive Analysis and Multiple Linear Regression. The results of the descriptive analysis show that the procedures for funding fishermen's enterprises can be sourced from self-funding, family, and non-formal sources referred to as "container", with a value of 3.94 categorized as easy. The multiple linear regression analysis results yielded the equation Ŷ = 17.465 + 0.477X1 - 0.306X2. The research results indicate that funding procedures positively and significantly impact the decision to borrow from non-formal sources. Meanwhile, socio-economic conditions negatively and significantly affect the decision to borrow from non-formal sources. There is a positive and significant simultaneous influence between funding procedures and socio-economic conditions on borrowing from non-formal sources. The variable model can predict borrowing decisions from non-formal sources by 52.2%, with 47.8% influenced by other variables
